Technical Field

[0001] This utility model belongs to the field of pipe jacking construction technology, and in particular relates to a detection device used in pipe jacking construction. Background Technology

[0002] Pipe jacking is a trenchless construction method, a technology for laying pipelines with little or no excavation. In pipe jacking, the jacking equipment in the working pit generates jacking force to overcome the friction between the pipe and the surrounding soil, pushing the pipe into the ground at the designed slope. The excavated soil is then removed. After one section of pipe is pushed into the soil, the second section is lowered and the jacking continues.

[0003] During the exploration process, the exploration personnel push the exploration device to locate the jacking drill bit that is being constructed, and to detect the location and depth of the jacking drill bit. Traditional exploration devices are fixed in shape and are not suitable for exploration personnel of different heights, which makes them inconvenient to use. Utility Model Content

[0006] Furthermore, the sensitive adjustment assembly includes a fixed plate, a bidirectional screw, an adjusting block, an adjusting rod, a connecting plate, a limiting post, and a display screen, wherein:

[0007] The fixing plate is fixedly connected to the top of the fixing frame and is symmetrically distributed.

The limiting post is fixedly connected to the bottom of the connecting plate and is symmetrically distributed in pairs. The lower end of the limiting post vertically passes through the fixing frame and is slidably connected to it. The display screen is located on the top of the connecting plate.

[0008] Furthermore, the sensitive adjustment assembly also includes a worm gear, a worm, a servo motor, and a top plate, wherein:

[0022] like Figure 1-2 As shown, a detection device for pipe jacking construction includes a base 1, a fixing frame 2, casters 3 and a detection radar 4. The fixing frame 2 is fixedly connected to the top of the base 1, the casters 3 are movably connected to the bottom of the base 1 and are symmetrically distributed in pairs, the detection radar 4 is fixedly installed at the bottom of the base 1, and also includes a sensitive adjustment component, which is located at the top of the fixing frame 2.

[0023] The use of sensitive adjustment components facilitates data observation by staff and increases the flexibility of use.

[0024] like Figure 1-4 As shown, to facilitate data observation by staff of different heights, the sensitive adjustment assembly includes a fixed plate 5, a bidirectional screw 6, an adjusting block 7, an adjusting rod 8, a connecting plate 9, a limiting post 10, a display screen 11, a worm gear 12, a worm 13, a servo motor 14, and a top plate 15. The fixed plate 5 is fixedly connected to the top of the fixed frame 2 and is symmetrically distributed. The bidirectional screw 6 is rotatably connected between the opposite side walls of the fixed plate 5. The adjusting block 7 passes through the bidirectional screw 6 and is threadedly connected to it, and is symmetrically distributed. The connecting plate 9 is located above the adjusting block 7, and the adjusting rod 8 is movably connected to the adjusting block. Between 7 and connecting plate 9, limiting posts 10 are fixedly connected to the bottom of connecting plate 9 and are symmetrically distributed in pairs. The lower end of the limiting posts 10 vertically penetrates the fixing frame 2 and is slidably connected to it. The display screen 11 is located on the top of connecting plate 9. The worm gear 12 is fixedly connected to the middle position of the bidirectional screw 6. The servo motor 14 is fixedly installed on the top of the fixing frame 2. The worm 13 is fixedly connected to the output end of the servo motor 14. The worm 13 and the worm gear 12 mesh with each other. The top plate 15 is fixedly connected to the top of connecting plate 9 and is symmetrically distributed. The display screen 11 is hinged between the opposite side walls of the top plate 15.

[0025] The height of the display screen 11 is adjusted by using the meshing transmission between the worm gear 13 and the worm wheel 12 and the bidirectional screw 6 to drive the adjusting rod 8 to move relative to or in opposite directions.

[0026] To facilitate stable support for the whole system, a hydraulic rod 16 is fixedly connected to the base 1, and it is symmetrically distributed relative to the detection radar 4. The free end of the hydraulic rod 16 is fixedly connected to a support plate 17.

[0027] Among them, the fixing frame 2 is arranged in a ∩ shape.

[0028] In practical use, the limiting post 10 can be used as a handle when the whole unit is moved. When the whole unit needs to be placed stably, the hydraulic rod 16 is extended to allow the two sets of support plates 17 to provide stable support for the whole unit. The detection radar 4 emits electromagnetic waves, which can locate the position and depth of the jacking drill bit. The detected results are displayed on the display screen 11 in the form of an image. If the height of the display screen 11 needs to be adjusted before the operator observes the data, the servo motor 14 is controlled to rotate at a constant speed. The meshing transmission of the worm gear 13 and the worm wheel 12 is transformed into the uniform rotation of the bidirectional screw 6. The adjusting block 7 moves relative to or towards the limiter under the limiting action of the limiting post 10, thereby adjusting the lower end position of the adjusting rod 8 to adjust the height of the display screen 11. After the adjustment is completed, the worm gear 13 and the worm wheel 12 have a self-locking effect and good stability. The above makes it convenient for operators of different heights to observe data.
